The Hierarchical internetworking model is a three-layer model for network design first proposed by Cisco in 1998. [1] The hierarchical design model divides enterprise networks into three layers: core, distribution, and access.
The three-tier is the common network architecture used in data centers. [10] However, three-tier architecture is unable to handle the growing demand of cloud computing. [11] The higher layers of the three-tier DCN are highly oversubscribed. [3] Moreover, scalability is another major issue in three-tier DCN.
The most widespread use of multitier architecture is the three-tier architecture (for example, Cisco's Hierarchical internetworking model). N-tier application architecture provides a model by which developers can create flexible and reusable applications. By segregating an application into tiers, developers acquire the option of modifying or ...

Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. [1] The process can be tailored according to each new network or service. [2]
